I am having trouble with these problems. I dont understand the function of s and t

Using a Quadratic Equation Problems A ball is thrown vertically upward from the top of a building 112 feet tall with an initial velocity of 96 feet per second. The distance s_(in feet) of the ball from the ground after t seconds is s (t) = 112 + 96t - 16t2 Complete the table and discuss the interpretation of each point. s(t) Interpretation 0 0.5 2 100 100 200 200 Answer these questions. 1. After how many seconds does the ball strike the ground? 2. After how many seconds will the ball pass the top of the building on its way down? 3. How long will it take the ball to reach the maximum height? 4. What is the maximum height?|
